METHOD AND MEANS FOR FIXING SHANK STIFFENERSI N SHOES.

Application filed June 12, 1324. Serial No. 719,678.

To all whom it may concern:

Be it known that I, REINHARD 'E. BARTELS, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Methods and Means for Fixing Shank Stifieners in Shoes, of which thefollowing is a specification.

This invention relates to shank stiffeners and the method of fixing them in shoes, relating more especially to the attachment of the stiffeners at their forward ends. Their forward ends are located adjacent to the break line of the sole andit is important that no portion of the attaching means should project above .the surface of the innersole at this point in a manner to cause discomfort to the wearer. The fastener is attached while the shoe is on the last and at this part of the last there is no metal plate as at the heel against which stiffener fastening means driven through the innersole may tallic device positioned on the inner face of the innersole and bearing on the last and which serves as an anvil for supporting an innersole where the fastener is to be clinched. This not only insures proper clinching of the fastener but also prevents it from presenting a rough projection on the interior of the shoe and alsofrom injuring the last.

For a more complete understanding of this invention reference may be had to the accompanying drawings in which Figure 1 is an inverted plan of a lasted welt shoe showing the anvil member in position.

Figure 2 is a fragmentary section on line 2-2 of Figure 1.

Figure 3 is a view similar toFigure 1, but showing the shank stiffener in position ready to be fixed to the innersole.

Figure 4 is a fragmentary section on line 44 of Figure 8.

Figure 5 is a section to a larger scale on line 5-5 of Figure 4. V V a Figure 6 is a section on line 66 of Figure 5. d

Figure 7 is a view similar to Figure 5, but showing the stiffener fixed to the innersole.

Figure 8 is a fragmentary section on line 8-8 of Figure 7. a

In carrying out this invention at the point where the forward end of the shank is to be attached, the innersole 1 is perforated, as

driven into the innersole. also acts to flatten out the head of the paper I shown at 10 in F igure l, and before the innersole is tacked to the last a headed me- 7 tallic member 11 has its shank 12 passed through this perforation, the head of this member (resting against the inner face of the innersole so that when the innersole is tacked to the last it bears between the surface of the last and the innerso-le,as shown clearly in Figure 2. This headed membermay be of any suitable description, but a round headed paper fastener such as isfcoinmonly employed to fasten sheetsof paper together has been found suitable Such a fastener comprises a narrow metal strip folded on itself to form a flat intermediate portion a (Figure 5) over which a round head 6 engages, the ends of the strip forming a split shank which maybe separated and the ends bent down on to the material through which the shank is passed.

After the shoe has beenlasted and it is desired to fix the shank stiffener in position, it is, placed on the exposed face of the innersole as shown in Figures 3 and 4. The

shank stiffener is provided with a perforation 1 5 through which the shank 12-. of the paper fastener, or other headed member,

may extend, and projectingjfrom the face of the stiffener adjacentto the innersole are shown a pair :of integral attaching prongs 16. By pressing thesefro-m the body of the shank stiffener, the hole 15through which the shank of the headed member extends, is formed at the same time. It will be noted also that these clinching points or prongs are sufficiently close together to lie within face of the stiffener. Where a paper, fastener is used as the headed member, the opposite ends of the strip of sheet metal comprising the shank of the fastener-are sepa: rated, the two ends being bent slightly in' opposite direct1ons,,so-that by striking a single blow vwiththe hammer these ends are I bent down against the shank stiffener" as shown at 17 and '18 in Figure 7, at the same time that the attaching prongs 16 are The same blow fastener so that it offers noobjectionable projection on the inner face of the innersole. The rear end of the shank stifiener'may be provided with prongs-' which may be driven into the innersole to fix this end of the stifiener in position in the usual manner:

'As herein shown the stiffener comprises two strips of sheet material and26 fixed in face to face relation, the strip 25 having its central portion laterally curved to form a beaded portion 27 extending longitudinally thereof. It might be otherwise constructedthowever, without departing from the spirit or scope of this invention. Likewise in place of forming the prongs 16 integral with the stiffener other fastening means for the forward end of the shank stiffener may be employed, provided they are of such a nature that they'may'be clinched within the area of the headed member so that this may serve as an anvil therefor.

Having thus described an embodiment of this invention it should be evident to those skilled in the art that various changes and modifications might be 'madetherein-without departing from' its spirit or scope as defined by the appended claiins.

I claim:

1. The method of attaching shank stiffeners to shoes which-comprises inserting the shank of a headed metallic member through asole member of theshoe, the head being on the opposite side of the sole ineniber from the stiffener, placing the stiffener in position and inserting fastenmgs for said stiffenerinto the opposite'side of the sole member'from said head area thereof. r V i 2, The method of attaching'shank stiffeners to shoes which comprises inserting the and clinched within the shank of a headedmetallic member through asole memberof the shoe, the head being onthe opposite side of the sole member from the stiffener, placing the stiffener in position with fastenings at the opposite side of the sole member from said head to be clinched in said sole member within-the area of said head, and bending the shank of said headed member over the exposed face ofsaid stiffener and clinching said fastenings. Y

3. The method of fixing a shank stiff cner to an innersole which comprises inserting thershank of a headed metallic member through the innersole at a desired fastening point. with its headlying on the upper facethereof before the soleiis tacked to the last5 andaftetthe lasting operation placing a' pronged'shankstiffener in position on the outer face of the innersole with the prongs opposite to, said head; and driving the prongs into the innersole within the area of said head.

4:. The'method of fixing a shank stiffener to an innersole which comprises inserting -the shank of a headed metallic member through the innersole at adesired'fastening point with its head lyinglonthe upper face thereof before'the sole is tacked to the last, and after the lasting 'operation placing a" pronged shank stifl'ener in position on the outer face of the innersole with the prongs opposite to said head, and driving the prongs into, the "innersole within. the area of said head and bending theshank of said headed member over said stiffener.
